Back as a coach this season after taking a break to spend time with her 6-month-old daughter Summer Rain, Aguilera received a warm welcome from Blake Shelton and Adam Levine when she returned, as seen in the exclusive behind-the-scenes clip below.

"Christina Aguilera, I missed you so much," says Levine. "I love you. It's great to have you back." Adds Shelton: "Not a lot's changed … Adam is still immature [and] I still drink as much as I used to."
